Wilson was the group’s baritone singer until 1977. During those years, the Blue Notes became one of the biggest Philly Soul acts, well known for their immaculate harmonies. Wilson helped back late lead singer Teddy Pendergrass on many classic hits from this era, including “If You Don’t Know Me By Now” (listen after the jump) and “Wake Up Everybody.”
